In "Of Mice and Men", what's one quote that shows that Curley's wife is not bad or a "tart", but just lonely?

Although Curley's wife's chief complaint appears to stem from dissatisfaction with her life on the farm, there is no doubt but that she is lonely as well.  Because of her flirtatious nature and Curley's insane jealousy, none of the ranch hands will associate with her, and so her only companionship comes from Curley, about whom she says,

"Sure I gotta husban'.  You all seen him.  Swell guy, ain't he?  Spends all his time sayin' what he's gonna do to guys he don't like, and he don't like nobody".

Curley treats his wife like a possession and does not give her the companionship and attention she craves.  She is isolated on the ranch, and she laments her loneliness and boredom, saying,

"...Sat'iday night.  Ever'body out doin' sum'pin'.  Ever'body!  An' what am I doin'?  Standing' here talkin' to a bunch of bindle stiffs - a nigger an' a dum-dum and a lousy ol' sheep - an' likin' it because they ain't nobody else" (Chapter 4).
